Returning to the previous subject of conversation, Heideck said to the Lieutenant-Colonel:  “I don’t think we need trouble ourselves any more about the communications of Countess Arselaarts and Messrs. Amelungen and Co.  The court-martial may settle with them.  I attach incomparably greater importance to skipper Brandelaar, whom I hold in my hand, and through whom—­perhaps with the help of Camille Penurot—­I hope to obtain information about the British fleet and its proposed employment.  Brandelaar’s vessel should now be off Ternenzen.  I will ask you, Herr Lieutenant-Colonel, to have the man and his crew arrested to-day.”

“But how does that agree with your intention of using him as a spy in our interest?”

“I forgot to tell you that it is an agreement between Brandelaar and myself.  He himself thought it necessary for his own safety; he was afraid of the crew.  Of course it will only be a sham examination, and the man must be released as soon as possible, on the ground of insufficient evidence, so that he can return to England to-morrow.”

The Lieutenant-Colonel promised to do as the Major desired.

The same evening Heideck met Penurot by arrangement at a tavern.

“Our business is somewhat complicated,” said Heideck.  “There must be some more people working for your father, hitherto unknown to us.”

“Why do you think that, Herr major?”

“Your father had some letters from Admiral Hollway, which were not brought by Brandelaar.”

“Yes, yes, I know.  I can imagine that.”

“Do you know who brought them over?”

“I don’t know for certain, but I can guess.”

“Can’t you get me more certain information?”

“I will try.”

“How will you set about it?”

“There are some sailors’ taverns here, where I hope to get on the track.  But they are desperate fellows, and it is dangerous to meddle with them.”

“If you will point out the taverns to me, I will have all the customers arrested to-night.”

“For Heaven’s sake, don’t, Herr major!  We should ruin everything by that.  These men would let themselves be cut to pieces rather than betray anything to you.  If anyone can get them to speak, it is myself.”

“Wouldn’t you be trusting them too much?”

“No, no.  I know best how to deal with them, and I know many ways of making them open their mouths.”

“Well, do what you can.  The matter is important.  I am very anxious to find someone to obtain trustworthy information about the British fleet, and you know we don’t spare money.”
